Froedtert South St. Catherine’s Medical Center Campus

Pleasant Prairie, Wisconsin

Riley Construction completed the major expansion of Froedtert South’s St. Catherine’s Medical Center, more than doubling its total size by expanding and renovating approximately 322,000 SF. This project involved a three-story, vertical expansion on top of an active, full-service hospital facility. The facilities expansion and renovation meet growing patient expectations for private rooms and more upscale facilities.

The project included expanded emergency and urgent care departments, five new operating rooms, childbirth services department, women’s health, and obstetrics unit, 24 new patient rooms, third-floor shell for future inpatient rooms or departments, a mobile technology garage, a maintenance garage and additional loading dock.

The project also included major retrofit and expansion of the central plant. All work was performed while maintaining full operation of critical areas of the hospital.
